O pupário de Raphiocera armata (Wiedemann, 1830) é descrito com base em duas larvas criadas em laboratório, coletadas na Ilha da Marambaia, Estado do Rio de Janeiro, Brasil. Este registro se constitui na primeira descrição da larva de uma espécie da subfamília Raphiocerinae e associa este grupo de moscas com o ambiente aquático, corroborando a hipótese de Woodley de relacionamento filogenético de Raphiocerinae com Stratiomyinae e Nemotelinae baseado no modo de vida aquático das larvas.

The puparium of Raphiocera armata (Wiedemann, 1830), based on two larvae reared in the laboratory, collected at Ilha da Marambaia, State of Rio de Janeiro, Brazil is described. This record constitutes the first description of the larvae of a species of the subfamily Raphiocerinae, and associates this group of soldier flies with the aquatic environment, corroborating Woodley's hypothesis of phylogenetic relationships of Raphiocerinae with Stratiomyinae and Nemotelinae, based on the aquatic mode of life of the larvae.

Os pupários de Cyphomyia aurifrons Wiedemann, 1830 e Cyphomyia picta Schiner, 1868 são descritos pela primeira vez. As larvas foram coletadas sob a casca de árvores caídas em uma floresta tropical situada na Ilha da Marambaia, Estado do Rio de Janeiro, Brasil, (23º04'15"S, 43º53'59"W, nível do mar, aproximadamente 42 Km²). Notas biológicas são fornecidas.

The puparia of Cyphomyia aurifrons Wiedemann, 1830, and Cyphomyia picta Schiner, 1868 are described for the first time. The larvae were collected under the bark of fallen trees in a tropical rain forest at Ilha da Marambaia, State of Rio de Janeiro, Brazil, (23º04'15"S, 43º53'59"W, sea level, approximately 42 Km²). Some biological notes are also presented.

The larva of Popanomyia femoralis and puparium of Engicerus major are described. The larvae were collected under the bark of fallen trees in an area near the tropical rain forest at Ilha da Marambaia (23º 04'15''S-43º53'59''W-sea level) and Cabo Frio (22º52'46''S-42º01'07''W-4 m), State of Rio de Janeiro, Brazil. Biological notes are presented. The larva of Popanomyia femoralis and puparium of Engicerus major are compared with those of Chalcidomorphina aurata Enderlein, Cosmariomyia argyrosticta Kertész, Dactylodeictes lopesi Lindner and Vittiger schnusei Kertész, other species of the same subfamily.

Herein, the puparium of Sargus thoracicus Macquart, 1834 collected in decaying organic material, on the Campus of Universidade Federal Rural do Rio de Janeiro, Seropedica, Rio de Janeiro State is described. The description is based on a single larva collected and reared in laboratory till the emergence of the adult. Some biological notes on the larva are also presented.

The larva of Cosmariomyia argyrosticta Kertész, 1914 and the puparium of Dactylodeictes lopesi Lindner, 1964 are described for the first time, based on four larvae and 10 puparia and one puparium respectively. Larvae were collected under the bark of fallen trees in an area near of tropical rain forest at Iguaba Grande (22º50'21"S, 42º13'44"W, 18 m) and Buzios (22º44'49"S, 41º52'54"W, 3 m), State of Rio de Janeiro, Brazil. Some biological notes are also presented. The larvae of Cosmariomyia argyrosticta and Dactylodeictes lopesi are compared with Chalcidomorphina aurata Enderlein, 1914 and Vittiger schnusei Kertész, 1909.
